Gentlemen,
I'm having a small issue with my 1980 srx 440 only pumping fuel into one of the fuel lines. The generator side carb is getting a nice flow of fuel, but the clutch side only seems to trickle. I put all new fuel lines and vacuum line on with zip ties, cleaned the carbs and a new fuel filter before the fuel pump. I just took the pump off and took it apart and I found what looked to be the remains of a bug in the pump. It was stuck in the area of those two small round clear plastic diaphrams, but it wasn't big enough to plug any of the fuel ports. None of the ports were plugged and the pump looks fairly new. The pump diaphrams all look good with no rips or tears. It's a stock Mikuni pump with the two fuel output lines coming off the same section/block.
I bought the sled a few months back and this is the first time I've had a chance to really run it. When I got it running after I cleaned the carbs, it ran real strong. I rode it around for a little while and it started to bog a little. I shut if off and checked the lines and that is when I noticed this problem.
I ordered a new fuel pump and will have it on this weekend, but this really has my curiousity. I've worked on a lot of sleds in the past, but never with a problem like this.
Any ideas?
Thanks all.
